ELECTRIC sWITCi-I,

To all whom it may Concern Be it known-that I, CHARLEsJ. KLEIN', a

citizen 'of the United States, residing at l cise, and exact description,

` had to the accompanying drawing, forming Milwaukee, inthe county of Milwaukee' and State of Wisconsin, have invented new and useful Improvements in Electric Switches, of which the following is a full, clear, conre'ference Vbeing a rpart of this specification.

his invention relates to electric switches and more particularly to those of the feed.

through type. f i

The invention has among `its objects to provide'such a switch of simple and. compact construction and.Y one of such external dimensions and shape as tobe conveniently -handled and to i beattractive in appeai'ance.-

In my prior patent No. 1162864, granted Dec. 7,1915', there is discloseda so-called feed-through switch for like uses where- -in the switch mechanism is completely in-A closed in Ea two-part insulating casing having'` end openings for circuit. wires and a Jthrough passage for one circuit wire,sa'id casingbeing divided along a plane whereby i separation of, its. parts gives access to the contact terminals of theswitchmechanismv and opens thethrough wire passage lengthwise.i Such a switch has been found to possess numerous important advantages over toA provide a further improved -switch Aof such character.

More specifically the invention has among itsvobjects to provide Va switch for the aforesaid and other uses wherein the switch parts and cndiictor passages are4 so arranged in 1 'the insulating Acasing as to facilitate manufacture, assembly, inspection and wiring. .,Anothcr object is to provide a switch for A.the aforesaid andother uses wherein the iii- V'partsand conduc or passages so arranged sulating casing is so divided and the switch as to permit. ofv the use of various switch mechanisms and various formations ofthe u cas-ing while maintaining suitable external dimensions of the latter.

lAnother object is to provide a switch for the` aforesaid and other uses whereiithe switch'parts and conductor passages are so arranged that the insulating casing may be Figure 1 is i .specification of Letters Patent.l Patented Sept 14" 1920 Application mea noviiier 24, 1916. serial ivaiaaioa vflattened to rest i'n one or more given posi- Vtions renderingv the switch operatingmem'- ber or members. readily accessible and conveniently operable.

.Other objects will hereinafter appear. In the accompan ing drawing, wherein is llustrated `an em odiment of -the invenion- a front elevational viewI of the switch; Q f- 2 a side elevation of the same; Eig. 3' is an' interior elevation of one sec'-` tion of the casing showing the switch mechanism;

Fig.4 is a similar view,.of the tion of the casing; and, .i

Fig. 5 is-a section'of the switch mechanism and casing substantially on line 5-5 of Ieferring to the drawing, a switch mechlanism a is inclosed within a casing comprising similar sections b and Jcl which are recessed to receive the same and are preferably composed of insulating material.' The specific switch mechanism shown in the drawing is to be considered asillustrative vonlygas many other .kinds andtypes of switch mechanisms may be utilized and could be used for-the same' purpose by those skilled in the lartwithout departing from the spirit and scope of the. invention as set. outJin the appended claims. i

other sec-v The speciiic switch mechanism as shownl in the drawings is of the push' button type and in certain respects is similar to the hill and valley switclL described and claimed in my Patent No. 1,184,104, dated May 23, 11916, which may be briefly described as folows:

` A fixed stud 1l ispermanently anchored.

at the center of the recessed'portion of the casing section b and constitutes a support for the movable switch' elements which include a reciprocating operating'member and van oscillating contactor. rThe operating f membersf'i's providplfwith a slot 3 whereby the sa'm'eis mounte or reciprocation'upon .the stiid 1 while hill and valley cam members 4 and 5 project fromopposite sides of said operating member for'actuation of the contacter 6 which is pivotedupon the stud 1 and provided with downwardly projecting knobs 7, 8 for direct'engagement with the lrespectiihei'cam surfaces 4, 51.

A helical spring iscoiled-about the'stud'l and serves to maintain th vv1;, yie1ding enga ment Vrwith the voperating "f Vn i'ember. where iixed cooperating contacts 10,11.

y upon reciprocation 'of the latter the-.conta break' circuit between vThe said fixed contacts.- are, attached -to thecasing section `b by means of .xedstuds v ready stated, isadapted to serve `asia feed e' contactor inl permanentsaid switch. ctor is oscillated with a'snap through switch in conjunction with 'a" iou'ble Inwiringiand'assembling the one'oi the 4conductors is'cu't and conductor."

Such an arrangement of switch parts and Other grooved channels 20, y21 Y conductor passages is very advantageous in Thus the swit gradually rises from, the surfaceof conductor inserted in the groovesifromithe lowermost position ofthe conductor inlet to the face of the casing. Curved abutments 24, 25 having their faces flush with the face of the casing section closely surround the recessed portion. of said section kand serve to 'mentioned from 'separate the various grooved channels above sald recessed portion and from each other, while screw sockets 2.6 and the section?) above described but of the section 32, 33 and 34, vresponding to of-the opposite section. `The however, do notterminate asdo the correthe two sections arefzunited.l

`said section .the push button gro 27 are located within said abutments to be .engaged by suitable screws 28, 29 for unit- 1n 4.5

eferring more particularly to Fig.` 4, thel section c is in most respects similarito is recessed er portion of its-extent. The urthermore is-provided with pushbutton grooves 30, 31 similar to those c and with conductor'grooves 35, registering with and corthrough a lar grooves 34.-, 35,

Moreover, as will be ap arent, the compactness of parts permits o consider-l ch -is adapted for support in able. latitude in the. shaping., of the.l casing without undulyvincreasing the dimensions thereof. j

The casingsections. as so constructed may' be'readily molded and with slight modifica- 'Y tions'may be adapted for inclosure oi various 'different switch mechanisms/''. Also, vsuchfconstruction of, the casing facilitates mounting of the switch mechanism therein and inspection of said mechanism thereafter" and all parts of the mechanism being fixed .to one section of the terminals and through wire p assage readily accessible 'the switch may e quickly and `l easily wired. `As will be understood, the
